Audio Signal Processing for Unmanned Aerial Vehicles Audition
Subject: Audio Signal Processing for Unmanned Aerial Vehicles Audition
When: Tuesday, February 7, 2023 11:00 AM-12:30 PM.
Where: Building 115, Brian Anderson, A201, Godel Room
Speaker: A/Prof. Yusuke Hioka (University of Auckland, New Zealand)
Abstract:
Along with the rapid advancement of its technologies and expanding abilities, new applications of unmanned aerial vehicles (UAV, a.k.a. drones) have been actively explored over the last decade. One of such emerging applications of UAV is its use for recording sound, i.e. equipping UAVs with “auditory” function, which has a huge potential to deliver both commercial and societal benefits through various industries and sectors, such as filming/broadcasting, monitoring/surveillance, and search/rescue. However, a challenge with the UAV audition is the extensive amount of noise generated by the UAV’s propellers, known as ego noise, significantly deteriorating the quality of sound recorded on UAV. Research in signal processing for better UAV audition has been actively conducted to achieve better auditory function by addressing this challenge. This talk will overview recent studies on audio signal processing for UAV audition at the Communication Acoustics Laboratory of the University of Auckland, with a particular focus on techniques to emphasise sound from the target source while minimising the propeller noise. The talk will also introduce a case study where such technology is applied to commercial products.
Bio:
Yusuke Hioka is an Associate Professor (full professor in the American system) at the Acoustics Research Centre of the Department of Mechanical and Mechatronics Engineering, the University of Auckland, Auckland, New Zealand. He received his B.E., M.E., and Ph.D. degrees in engineering in 2000, 2002, and 2005 from Keio University, Yokohama, Japan. From 2005 to 2012, he was with the NTT Cyber Space Laboratories, Nippon Telegraph and Telephone Corporation (NTT) in Tokyo. From 2010 to 2011, he was also a visiting researcher at Victoria University of Wellington, New Zealand. In 2013 he permanently moved to New Zealand and was appointed as a Lecturer at the University of Canterbury, Christchurch. Subsequently, in 2014, he moved to the current position at the University of Auckland as a Senior Lecturer. Currently he is also the Co-director of the Acoustic Research Centre and leads the Communication Acoustics Laboratory at the Centre. His research interests include audio and acoustic signal processing, room acoustics, human auditory perception and psychoacoustics. He is a Senior Member of the IEEE and a Member of the Acoustical Society of Japan and the Acoustical Society of New Zealand. Since 2016 he has been serving as the Chair and Vice Chair of the IEEE New Zealand Signal Processing & Information Theory Chapter.
